Authors have contributed their most interesting findings in dealing with patients suffering of other diseases simultaneously, such as diabetes, cardiovascular disease and other health problems. Each chapter has been thoroughly revised and updated so the readers are acquainted with the latest data and observations in these complex cases, where several aspects are to be considered. The book is comprehensive and not limited to a partial discussion of hemodialysis. To accomplish this we are pleased to have been able to summarize state of the art knowledge in each chapter of the book. This book provides practical and accessible information. It is quite comprehensive as it covers various special circumstances in hemodialysis patients and their treatment. We wish to thank each author for taking considerable time and effort to ensure their chapter provides state of the art information. We hope that readers achieve the same level of acquisition of new knowledge as we have attained by editing this book.

Results in other CRF patients, such as patients with uremia but not on dialysis, or patients on HD, have yielded conflicting results Three studies demonstrated delayed gastric emptying in uremic predialysis patients (31-33) The researchers have also documented delayed gastric emptying in hemodialysis patients particularly patients who are hypoalbuminemic (32, 33) In our study, as for total protein, the... GERD in CRF patients who underwent HD (24.2%) was increased In the gastroendoscopic findings of the 156 CRF patients who underwent endoscopic examination, the prevalence of GERD was 34.0% Especially, in symptomatic cases, the prevalence of GERD was 44.0% (7) Although we are now aware of the increasing prevalence of symptomatic GERD in HD patients, little is known about the gastroendoscopic findings... HBV-DNA assays In this context, it is of note that several authors consider occult HBV as a possible source of virus spread in hemodialysis units, thus representing a risk of infection for both patients and staff, and suggest some precautions including HBV DNA screening for all hemodialysis patients (Minuk et al., 2004) 13 HBV variants in the general population vs among hemodialysis patients In this topic,... diagnose GERD in this study We diagnosed GERD in those with a score of four points or more In these 418 stable HD patients, the prevalence of GERD was 101 patients (24.2%) (Table 1) (4) Compared to the reported prevalence of GERD in Japan (16.3%) (6), the prevalence of GERD in CRF patients (24.2%), especially who underwent HD, is increased This increased prevalence of GERD in HD patients was in accordance... living in areas where HBsAg prevalence is 8% or higher, with a risk of infection of more than 60%, mostly during the childhood and with a high risk of chronicity Forty-three percent of worldwide infected people are living in areas of intermediate prevalence with risk of infection of 20-60%, occurring across all age groups Only the remaining 12% are living in areas of low prevalence with risk of infection... HBV infection in patients undergoing regular hemodialysis in the developed world is currently low (Finelli et al., 2005) In developed countries, where the infection control procedures have been implemented, HBV infection declined significantly, reaching HBsAg rates lower than 1.0% (Alter et al., 1986; Tokars et al., 2002) However, outbreaks of HBV infection continue to be reported occasionally in dialysis... worse, although we could not examine serum gastrin level (7) But hypergastrinemia may also be in part to due increased secretion, because the density of G cells is increased in CRF patients (15, 16) possibly owing to a hyperthyroid state Elevated serum gastrin causes an increase in acid production by the parietal cells However, when measured in CRF patients, large variations in the mean gastric acid production . provides an overview of special cases in hemodialysis patients.
